Title: Measuring flow velocity
IPC: G01P5/20
Filed: 1980-02-12
Abstract: The rate of flow of a strata 19 of a liquid seeded with extremely small gold particles is measured by illuminating the strata by a laser 1, by imaging reflections from the particles within the strata onto a diffraction grating 11, and by autocorrelating the photoelectrically 13 sensed output from the grating, and the system is characterised by the presence of high pass filters 21, and in that the optical imaging arrangement has a very small depth of field just deep enough to encompass the strata 19, whereby light originating from particles outside the strata 19 and from other reflectors outside the strata 19, such as boundary surfaces, is prevented reaching the grating. <IMAGE>
Patent GB-2047994-A (GB)
Title: Current balance earth leakage circuit breaker
IPC: H02H3/33
Filed: 1980-02-22
Abstract: An earth leakage circuit breaker, for use with a television receiver whose chassis is at a dangerous voltage level, comprises a core- balance transformer 22 whose secondary winding 28 senses any variation in flux due to current imbalance between the two primary windings 20, and supplies current to a relay coil 18 to open the contacts 16. The relay coil 18 operates in opposition to a permanent magnet which tends to hold the contacts 16 closed. A current generator 84 supplies a constant current which does not quite cause the contacts to open. This generator 84 is inoperative during initial switch-on of the circuit breaker due to an RC circuit 98, 96 in time delay 86, the circuit breaker maintaining a reduced sensitivity during this period. Thus, high sensitivity is obtained which is not limited by surge currents at switch-on. The core of transformer 22 is formed of alternately-stacked E and I shaped laminations and is of a size and material such that it loses its magnetism relatively rapidly after each use. The transformer primary windings 20 are bifilar wound with P.T.F.E. coated wire and the winding layers are interleaved with insulating material. <IMAGE>

Title: Clamp for Hoses and the Like
IPC: F16L33/03
Filed: 1980-11-06
Abstract: A clip useful for connecting fluid- conveying hoses and the like to couplings, valves and the like. The clamp is formed of a spring metal strip 10 which has portions of its longitudinal parallel linear edges 12 cut to provide a pair of parallel inclined linear edges 14 such that the original constant width of the strip is gradually reduced toward the longitudinal opposite ends of the strip so that the width of the strip varies in proportion to the bending moment produced in the strip, with the thus narrowed opposite ends being bent in mutually opposed relation to provide operating knobs 16 for forcibly spreading the ring diameter. The spring metal strip thus prepared is then wound into a ring of right circle, with the inclined linear edges abutting against each other along a given length, thereby ensuring uniform bending stress throughout the ring. <IMAGE>

Patent GB-2071886-A (GB)
Title: Diagnostic apparatus
IPC: G06F11/30
Filed: 1981-03-16
Abstract: A main processor 5 may transmit messages selected by itself to a diagnostic apparatus. It does so by writing information in a predetermined location in a writable microprogram control store. The diagnostic unit loads the address of that location into a reference address register 64 and sets an address comparison circuit 74 to respond only to write accesses. The address comparison circuit 74 then outputs a signal on a line 60 when it detects equivalence between that address and the address used in the control store access, held in an address input register 69. The output signal acts as an interrupt signal for a microprocessor system which subsequently causes a halt circuit 77 to halt execution of micro- instructions in the main processor. It then causes a control circuit 76 to carry out a read access of the control store at the predetermined address, held in an address output register 63. The data output is received in a data output register 62. <IMAGE>

Patent GB-2085546-A (GB)
Title: Scouring of elongate material
IPC: C23G/
Filed: 1981-10-13
Abstract: Wire (50) is passed through apparatus (51) having two treatment zones. The first treatment zone contains six wire cleaning heads (15-20) and the second treatment zone contains two wire cleaning heads (13 & 14). Each cleaning head consists of a primary cylindrical chamber (72) flanked by two secondary cylindrical chambers (73) of substantially smaller diameter. The wire passes axially through the cylinders. A working fluid such as dilute alkali, water or an organic solvent is pumped into the primary cylindrical chamber via a tangentially aligned inlet (74). It circulates in the primary chamber (72) and leaves via the secondary chamber with a very high annular velocity due to the reduction in the diameter of circulation. The high circulation speed causes vibration in and around the wire in the secondary chambers with resultant abrasion of the surface of the wire. In an alternative embodiment up to all but one of the cleaning heads may be replaced by dies. Separate fluids are used in each treatment zone and prevented from mixing by a jet of high pressure air directed obliquely onto the wire to repel any flow of fluid along the wire. Similar jets prevent escape of fluid out of the ends of the apparatus.

Title: Installation for producing methanol
IPC: C01B32/40
Filed: 1981-10-26
Abstract: The installation has both a hydrogenating coal-gasifier (1) and a methane-decomposition furnace (6), the latter preferably being heated by a high temperature nuclear reactor (25). The two gas mixtures obtained from the gasifier (1) and the furnace (6) are freed of carbon dioxide, and, when mixed, are supplied to a methanol- synthesis reactor (11). The methanol produced is separated in a separator (13) from the gas, and the latter is separated in a low temperature separation process (14) into its components. The hydrogen flows back to the gasifier (1) and the methane to the furnace (6), whilst the nitrogen is removed and the carbon monoxide is conveyed back to the reactor (11). By integration, the amount of hydrogen conveyed in the installation is greatly reduced, which leads to savings in piping, pumps, etc. The heating fluid emerging from the furnace (6) can be used to heat a steam producer (19) in the lower temperature range, with which vapour a turbo-generator (20, 21) is driven. Leakage steam is supplied to the furnace (6) from the turbine (20).

Patent GB-2119214-A (GB)
Title: Method of improving the growth of plants
Inventor: HALL TIMOTHY JOHN
IPC: A01G1/04
Filed: 1982-04-22
Abstract: The invention is concerned with the problem of how best to infect roots of a plant with the beneficial mycorrhizal fungus. Merely mixing the inoculum of the fungus with soil or other growth medium is time- consuming and not very effective. The invention lies in the idea of positioning across the path of growth of the roots a carrier material, carrying the inoculum. The roots are then allowed to contact and penetrate the carrier material, so that they pick up the inoculum and become infected. Preferably the carrier material is a sheet of cellulosic fibres coated with a layer containing the inoculum, which can also contain cellulosic fibres. The invention is useful in improving the growth of plants, particularly those grown in containers.
